Troopers said the eastbound lanes of I-80 were closed east of Colfax at 8 a.m.

The crash involved a charter bus and several semi tractor-trailers.

Witnesses said a semi truck lost control in the slick conditions and smashed into the cable barrier.

The bus crashed into the truck's trailer -- slicing it in half.

"Fortunately, nobody was injured. All the softball players on the bus were transferred to Newton by a Newton school bus. And then as result of the original accident we had additional accidents behind it," said Lt. Randy Kunert of the Iowa State Patrol.

A Simpson College spokesman Ken Fuson said the charter bus was carrying members of the Simpson College Softball team.

"We had no place to go, nothing to do other than to sit there and wait for the impact," said Head Simpson Softball Coach Henry Christowski.

Some 36 team members and coaches were on the bus during the crash. No one was seriously hurt.

"Everybody of course was thrown forward, and all of the glass was broken as far as the windshield was concerned," said Christowski.

Student athlete Britney Steele reported on Twitter that "Simpson Softball has an angel watching over us today. #Thankful" Another Tweet reports, "Mr Bus Driver, you are my hero."

"We have a couple parents on board and they were checking to make sure everybody was fine. They didn't want us to look out the window for fear we would see something we didn't want to," said Kacee Arey, a pitcher on the team.

The team was taken to a nearby Perkins restaurant, a new bus was brought in and the team started back on their journey eastbound on I-80.

"Other than being a little shook up over the whole thing, we were fortunate to have no more than some bumps and bruises. And as far as I am concerned, God was looking over us and protecting us," said Christowski.

The section of the interstate where the crash happened reopened about 11:30 a.m.
